To @ZZ 'whom t may concern:

Be it known that I, WILHELM H. CoMANs, of Roseland, in the District of West Kootenay and Province of British Columbia, Dominion of Canada, have invented certain new and useful mprovements in Turn- Flows; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of plows especially adapted for cutting ditches for irrigating purposes, the earth being thrown on either side of the ditch or furrow to save the manual labor of shoveling the earth from the ditch.

rEhe primary object of this invention is to provide a plow of this character which will be extremely light in weight and whereby the earth may be thrown to either side or to both sides, and may be utilized for throwing to the same side regardless of the direction of travel of the plow.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawing, Figure 1 is a plan view. Fig. 2 is a side elevation. Fig. 3 is a rear end view, and Fig. 4 is a modification of the plow point.

Referring to the drawings, 1 designates an approximately horizontally disposed beam from which depends a standard 2 in the form of spaced-apart members between the lower ends of which is secured a spacing block 3, and to the latter is secured a sole plate 5, which is preferably formed of steel. This plate is extended some distance forward and rearward of the standard, and is tapered at its front end to a point to receive the plow point 6. The latter may be either square at its forward end, as shown in Fig. 1, or pointed, as shown in Fig. 4. It is detachably secured in place by bolts 7 which fit in openings in strengthening bars 8 which are secured at their divergent ends, at 9, to the opposite sides of the standard, and at their forward convergent ends to the top of the sole plate by a bolt 10. As additional means for retaining the plow point I employ a bolt 12 projecting upwardly from` the sole plate and having a nut which lits in the under side of the cutter, as shown in Fig. 2.

13, 13, designate two side cutters and reflectors which are of triangular formation, and their lower forward ends are pivoted on a cross bolt 14: mounted in the sole plate in such manner as to allow a certain amount of lateral play. These members are divergently arranged, when in their lower positions, in reference to beam 1, and when so lowered they coperate in forming the ditch and serve to throw the earth from the latter in opposite directions. But when it is desired to throw the dirt only to one side of the ditch and to leave the other side practically straight, the member 13 of such latter side is thrown into the position shown in dotted lines, Fig. 2, which brings it into approximately parallel relation to the beam, and its now nearly upright edge cuts the soil along the edge of the ditch. For the purpose of manipulating these said members 13 I employ levers 15 which are fulcrumed on a cross rod 16 mounted in beam 1 and having its ends slightly angular. A spring-impelled retaining pawl 17, carried by each of the levers, is designed to engage a toothed segment 18 supported by crossrods 19, as clearly shown in Fig. 1. W'hen a side member 13 is raised by turning lever 15 its lower end will move slightly outward on the pivot bolt 14, allowing the upper rear end of the member to pass beneath a retaining plate 20 secured to the side of beam 1,

for the purpose of relieving the locking pawl 17 and the segment 18 from the weight of the side member when in its raised posi-` tion, which side member at its upper rear end is slitted to enable an offset linger 21 to be formed therefrom, and this linger is designed to pass between plate 2O and the `beam and by its tension when forced back of the plate said finger will act in holding the side member 13 in its raised position.

Vlhen either side member is raised so as to cut the side wall of the ditch, it is necessary that all of the soil be thrown toward that side of the plow on which the side member 13 is lowered, and for this purpose l employ a reversible mold-board 22 which is located centrally of the plow and in line with the inner end of the plow point. As clearly shown in Fig. 2, this mold-board is centrally mounted on a shaft 23, the forward end of which is supported by a bearing 24, in the form of an eye-bolt, projecting upwardly from the sole plate, and near its rear end this shaft is supported in a cross piece 25 connecting the side members of standard 2, as clearly shown in Fig. 3.

'lvVhile this shaft may be turned by the operator grasping the rear cranked end thereof, yet 'il provide for the automatic shifting ofthe mold-board by the raising of either side member 13. For this purpose each side member has a pin 26 projecting inwardly therefrom and which is designed to engage the mold-board beneath one of its longitudinal edges and thereby turn it and its shaft as the side member 13 is raised. Each of thev side members is also connected, at a point near its lower end, to standard 2 by a linl 27 which enables t the said member to be moved either close to the beam when being raised or away therefrom when being lowered.

ln practice, when it is desired to throw the earth on both sides of the ditch both side members 13 may be lowered as shown in Figs. l and 3, but when it is desired that only one of the said members shall be utilized for throwing out the earth and the other side member employed for shaping the side wall of the ditch, such side member is thrown into its inner upper position, as clearly shown in dotted lines in Fig. 2, and the act of throwing the said member into this position also effects the shifting of the mold-board to insure the discharge of the earth at one side of the ditch.

Vi/Yhile ll have not shown carrying wheels and their connecting axle, yet in practice it is lcustomary to mount lthe plow in this manner. y

l claim as my invention:

l.v A plow having a sole piece, a point detachably mounted on the forward end of the sole piece, and two divergently arranged side members extending rearwardly from the inner end of the plow point and capable of being eonjointly used for throwing the earth from a ditch, and means for holding either side member on a plane practically parallel with the longitudinal center of the plow to enable such side member to out the side wall of a ditch.

2. A plow comprising a beam, a standard Copies of this patent may be obtained for depending therefrom, a sole member, a ditch forming point on the forward end of such sole member, two divergently arranged side members pivoted at their forward ends to said sole member near the inner-end of the point, means connected to said members for raising them and moving them inwardly toward the beam, and means for holding the said members in their raised positions.

8. A plow comprising a beam, a standard depending therefrom, a sole member, two divergently arranged side members pivoted at their forward ends to said sole member near the inner end of the point, links piifotally connecting said side members to the standa rd and tending to hold them in their outer positions when lowered, means mounted on the beam for raising said side members and moving them inwardly toward the beam, and means mounted on the beam for engaging and holding said side members in their raised positions.

Ll. A plow comprising, in combination, a frame, a ditch forming point, two side inembers diverging from the sides of the frame from the inner end of the point, a moldboard extending from the inner end of the point and located centrally between said side members, means for shifting said meldboard, and means for raising and holding said side members.

5. A plow comprising, in combination, a frame, a ditch forming point, two side members diverging from the sides of said frame from the inner end of the point, a 'moldboard extending from the inner end of the point and located centrally between said side members, means for raising and holding said side members, and means for shifting the mold-board as said side members are moved into their respective positions.

In testimony whereof, I have signed this specification in the presence of two subseribing witnesses.
